Perfect speakers. I have owned ML Clarity's, Vantage's, and now 11A's. The new technology has produced an incredible advancement over the Vantage. I am running then through a Naim Uniti Nova and with a Rel S812 sub. They sound awesome. I run them in 2 channel for music and 7.1 for theater. They sound great for both applications. I replaced a set of Focal Sepora No3's with these and could not be happier. Although, the Focal's are incredible speakers, I love the stage sound from ML's. I understand everyone has their own opinion and many do not like ESL speakers, but I love the sound they produce. I have tried without the Rel sub and they poduce a great deal of base and I guess the Rel is overkill, they compliment each other wonderfully. If I hasd the space I would purchase another Rel S812 and run them in stereo. I do not have the room. I decided not to go with the 13A's because I have the Rel and I still believe the 11A's produce a great deal of bottom end without spending the extra money. I promise you will not be disappointed with these speakers.
